Even scientific research is affected heavily by this and requires fewer people to do the same job. In one week I can do experiments that 5 years ago would have taken 10 people a full year to perform. With such throughput it isn't necessary even to formulate a hypothesis. You just test every possible variation and let the data speak for itself.
You use the word science, I don't think it means what you think it means.
